interesting tidbit about protein and glasses

[Tubby]

Im in the middle of this class for babies, my wife is expecting in dec, an interesting subject was brought up about glass bottles. The nurse giving the class said NOT to use glass bottles because the protein sticks to the glass and the baby would not get the needed protein. Anybody ever heard of this and if that could equate to mixing my protein drink in a glass??? Im using plastic from now on...

Could that be why most shaker/mixer cups are made of PVC?

Hmm, Interesting.

When I mix my protein with water it sticks to the sides of the plastic blender. It also does somewhat when I use milk, but not as much. I don't think all of it sticks or even a large amount but some.
